PAGE-CORD LOCK.

SFECIFICATION forming part of Letters Patent No. 451,201, dated April 28, 1891.

Application filed August 13, 1890. Serial No. 361,868. (No model.)

To all whom it may corwern:

Be it known that I, HUGO STAEDING, of Kiel, in the Kingdom of Prussia, Germany, have invented an Improvement in Page-Cord Locks, of which the following is a specification.

My invention relates to a string-lock for set type, and has for its object to furnish an implement by means of which matter desired to be preserved in its set form may be locked and held by means of a string, thus avoiding the troublesome operation of tying the string around the matter by hand.

Vith this object in view my invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described, and afterward specifically pointed out in the claims.

Inv the accompanying drawings, Figure 1 is a view in side elevation illustrating my invention. Fig.2 is a horizontal section on the Fig. 3 is a top plan View, in which is shown an extension-bar for use when the form is larger than the lock. Fig. i is a perspective view of a galley with set type thereon and the string-lock, with the type locked ready to put away.

Like letters of reference mark the same parts wherever they occur in the various figures of the drawings.

Referring to the drawings by letter, g g are two plates made of iron, brass, copper, or any suitable material, connected together at each end by studs 1), which are riveted, screwed, or otherwise aflixed to the plates, in the present case being screwed at one end and riveted at the other. Between the plates, on each side of the center, are two rollers c c with journals in the plates, one journal of one of the rollers being provided with a square hole at the upper end for the insertion of a key. These rollers are provided with teeth 6 and e, which mesh with each other. These teeth are provided with a guard f, so that nothing will catch in them. The surface of the rollers is flattened on one side at (Z (Z, so that a space is left, through which the ends of the strings maybe readily passed by hand. One roller only may be flat and the other round, or one roller slightly eccentric, or one roller substituted by a fixed stud, or surface of roller may be grooved or even toothed to have more grip on the string, all without departing from the principle of the invention. In the upper plate is cut aslot 2' just over the teeth of one of the rollers. Secured under the head of the screw of one of the studsb at one end of the top plate is a pawl 71, bent to pass over part of the key-hole and its lower end passing through the before-mentioned slot cut in the plate and engagingwith the teeth of the roller below. The pawl must be pushed away from over the key-hole, so that the key may then be inserted, the pawl being made of spring-wire, which immediately returns it to its engagement with the teeth when the key is withdrawn.

a is the string which is to encircle the set type and have its ends between the rollers e and e. One end of the string a may be attached to the lock and the other around a roller, or it may be drawn through openings in the rollers provided for that purpose.

The operation of my invention is as follows: The string a being passed around the matter desired to be tied or locked securely, each end is passed over one of the studs 1) and from there over to the rollers, (which should have the fiat sides at the place for the string to be passed through,) when the ends are placed together and passed between the rollers. The pawl isthen removed from the teeth by the insertion of the key in the key-hole.

The key is then turned, which causes the rollers to rotate and brings the round parts of the rollers together, securely holding and carrying the string through. The key is turned-until the string is thought to be tight enough, when the operator holds the string to keep it from going back and withdraws the key from its hole, when the pawl again comes into engagement with the teeth of the roller and prevents it from turning back. The string may be left loose or folded or suitably fixed, and the type or matter is then readyto be put away untilwanted for use.

The advantages of my invention are obvious, there being none of the troublesome time generally had in tying up matter to be put away and there being no danger of pieing, as is generally the case.

hen the form to be tied is wider than the lock, spreader-plates Z may be used, as shown in Fig. 3, the string passing over their outer edges from the studs b. 'Jhese plates may be of any suitable size, and when the string is drawn tight by the rolls the plate will be firmly held against. the locked type.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In combination, the plates 9 g, the studs for securing the plates together and forming guides for the string, the toothed rollers geared together and journaled in the plates, and the pawl, as and for the purpose set forth.
